Assume a year has passed and there has been improved security by applying a number of controls. Using the information from Table 1 and table 2 in the attached document, calculate the post-control ARO and ALE for each threat category listed.
... What would be the budget for reducing or preventing that damage? ALE = SLE X ARO Give 1 in 3,000 of having a earthquake. ...ALE = ARO x SLE. ARO = 35%. ...
... Threat Category Cost per Frequency of ARO ALE Incident(SLE) Occurrence Programmer mistakes $5,000 1 per week 52.00 $260,000.00 Loss of intellectual property ...
... So the team takes the SLE value and multiplies by the ARO. In our case we will assign the value of 2 to the ARO. The resulting ALE value is $200,000. ...
